glCheckFramebufferStatus — check the completeness status of a framebuffer
GLenum glCheckFramebufferStatus(
|
GLenum target) ; |
target
Specify the target of the framebuffer completeness check.
glCheckFramebufferStatus
queries the completeness status of the framebuffer object currently bound to target
.
target
must be GL_DRAW_FRAMEBUFFER
, GL_READ_FRAMEBUFFER
or GL_FRAMEBUFFER
.
GL_FRAMEBUFFER
is equivalent to GL_DRAW_FRAMEBUFFER
.
The return value is GL_FRAMEBUFFER_COMPLETE
if the framebuffer bound to target
is complete. Otherwise,
the return value is determined as follows:
GL_FRAMEBUFFER_UNDEFINED
is returned if target
is the default framebuffer, but the default framebuffer does not exist.
GL_FRAMEBUFFER_INCOMPLETE_ATTACHMENT
is returned if any of the framebuffer attachment points are framebuffer incomplete.
GL_FRAMEBUFFER_INCOMPLETE_MISSING_ATTACHMENT
is returned if the framebuffer does not have at least one image attached to it.
GL_FRAMEBUFFER_UNSUPPORTED
is returned if depth and stencil attachments, if present, are not the same renderbuffer, or if
the combination of internal formats of the attached images violates an implementation-dependent set of restrictions.
GL_FRAMEBUFFER_INCOMPLETE_MULTISAMPLE
is returned if the value of GL_RENDERBUFFER_SAMPLES
is not the same
for all attached renderbuffers or, if the attached images are a mix of renderbuffers and textures, the value of GL_RENDERBUFFER_SAMPLES
is not zero.
Additionally, if an error occurs, zero is returned.
GL_INVALID_ENUM
is generated if target
is not GL_DRAW_FRAMEBUFFER
,
GL_READ_FRAMEBUFFER
or GL_FRAMEBUFFER
.
